Adam Levine's 'unrecognisable' new face is likely to be the result of a facelift and eyelid surgery, according to two aesthetics experts who have publicly analysed the Maroon 5 frontman's striking appearance at a Hollywood awards event in California on Saturday 18 April.

Levine, 47, stepped onto the red carpet at the12th Breakthrough Prize Ceremonyin Santa Monica clean-shaven, in a blue button-down shirt and black blazer, posing alongside his wife, modelBehati Prinsloo, 37. The couple, who rarely make public appearances together, smiled for the cameras and shared a kiss on the cheek. But it was not the reunion that set social media alight. It was Levine's dramatically smoother face and altered eye area, which many viewers said made him look almost like a different person.

The speculation around Levine's changed appearance has been driven not only by fans, but by professionals in the cosmetic field who say they believe they can identify the procedures involved.

Speaking toOK!,Chris Bustamante, DNP, NP-C, an aesthetic nurse practitioner and founder of Lushful Aesthetics, said he believed the singer had likely undergone surgical work before the event.

'He appears to have had surgical intervention via possible facelift with fat grafting and lower blepharoplasty to freshen his undereyes,' Bustamante said, referring to lower eyelid surgery. 'If fat grafting wasn't done, then it's likely surgical and some fillers or biostimulators. People are saying he looks drastically different or "overdone," but I think what we're seeing is work that hasn't fully settled yet. I think in a few months to a year, he'll look much more natural and refreshed.'

Levine and his representatives have not confirmed any procedures. Even so, Bustamante's view echoed what many online observers had already begun to suspect, that the change went beyond a new grooming style or better lighting.

He also suggested cosmetics may have amplified the reaction. Bustamante said Levine appeared to be wearing 'a lot more makeup than we're used to seeing,' adding that this 'works against him in regards to allegations of looking "too done."' In his view, the combination of possible fresh surgical work and heavier make-up may have made the transformation look even more dramatic.

Bustamante is not alone in arguing that Levine's eyes are the clearest sign of surgical change. In Beverly Hills, board-certified cosmetic dermatologist Molly Bailey has been even more direct.

'It's the upper bleph and I will [die] on that hill,' Bailey wrote beneath a red carpet video of Levine, using shorthand for an upper blepharoplasty, or eyelid lift. She later expanded on that view onInstagram, pairing humour with a technical explanation.
